Abstract

La présente invention présente un dispositif d'analyse dimensionnelle de particules (5) positionnées dans une zone sensiblement plane (8) comportant un moyen de prélèvement (4) de ces particules (5), un moyen de dilution (6) de ces particules (5), un moyen de positionnement (7) de ces particules (5) dans la zone sensiblement plane (8), une caméra (9) observant ladite zone sensiblement plane (8), un moyen de déplacement de la caméra (9) par rapport à la zone sensiblement plane (8), un circuit électronique (11) de traitement des informations sortant de la caméra (9) et un processeur d'analyse (12) des informations sortant du circuit électronique (11). La présente invention est en particulier adaptée à l'analyse de fibres de pâte à papier et à l'asservissement d'un raffineur de pâte à papier.
